I went to the Pt Townsend woodworking school to learn hnd cut dgovetails. Had a blast. One of the instruction sections involved bevel grinding a chisel with an 8” grinder and a white wheel and then taking a couple passes on Japanese stones to remove burr and to final sharpen the chisel. Wow. What a difference. The bevel grind offers two perfect registration points on the stone. Literally a couple of passes on my 4000 and 8000 grit combo stone and the chisel is sharp. And the edge holds well. No more rocking the chisel to find the flat of the bevel. Works great on plane irons. I’m using a free 3450 grinder with a 60 grit Norton white stone and the alee Valley tool rest.. Works great as long as I don’t overheat the tip. Just finished refurbishing some Stanley 750s from a buddy who used them to open paint cansand worse and they are better than new. Now what to sharpen next!

But I am retouching lathe chisels so generally I am going from the stone to wood… no additional stone work

Awesome you found a technique that works for you. that is always the key. too many buy a Tormek, which does a fantastic job, but requires farting around with set-up, and getting water from the house to refill it, so it often gets “postponed” until ALL the chisels are dull….then have a sharpening session. Where you SIGH>> Curse a little, and stop everything while you resharpen every tool in the shop.

I think what you are describing is Hollow grinding the tools bevel. The radius of the wheel leaves a slight hollow. The ground edge will rest on the tip and the heel of the grind when moving across the stones, making a more or less built in honing guide.This woks well for me also.
